Dew - Point Measurement System
General Description
For quality control and improvement in ferrous and non-ferrous industry, it is very important to adjust and control humidity. The measurement system is used to identify the relations of humidity and dew point by analyzing gas mixture ratio through gas chromatograph method and to measure dew point with algorithm during on-line process, thus enabling to monitor and manage on-line facilities.
| Principle & Method

- Analyze element gas spectrum from Gas Chromatograph

| System Configuration

- Gas Chromatograph

- Temperature Controller

- Gas Sampling Pump

- Main Controller

- Can be modified upon customer request

| Special Features

- Measuring dew point in gas of 600¡É or more

- Gas spectrum analysis by gas chromatographic method

- Monitoring the variation in dew point by continuous measurement

- Measuring high dew point of 50¡É or more
